Application June 26,1933, Serial No. 677,559

8 Claims. (G1. 72101) This invention relates to a furnace wallconstruction which includes a lining and means whereby the lining is supported upon the wall with facility for removing and replacing restricted areas of the lining without the necessity of taking down and rebuilding unimpaired portions thereof.

The invention resides in a special construction of support, as well as the combination into which it enters with the sustaining wall and lining of the furnace, which said support is constructed with a block-like body portion that adapts it to be manipulated as one of the units of which the furnace wall is built and thereby incorporated into and become an integral part of the masonry of that wall; and a bracket element which, when the body portion is incorporated in the wall, is presented in position to afiord vertical support for a key member of the lining and a horizontal interlock element which interengages with and anchors the said key member to the wall.

The principle upon which the support is used involves a distribution of a number of said supports at isolated points in vertically spaced horpizontal courses throughout the lined portion of the wall structure and corresponding with the desired distribution of key units of the lining structure, and with one of these key units vertically sustained and horizontally locked against n displacement upon each support, while intervening building units of the lining in each course of Supports will be sustained arch-wise, for instance, after the manner of a flat arch upon the said key units; and with an appropriate number of vertically spaced horizontal courses of lining units supported wholly from the furnace wall. The intervening spaces between these courses may readily be filled with easily removable lining units of convenient dimensions, so that when it becomes necessary to replace any portion of the lining the disturbance of the lining structure can be restricted to the immediate area concerned, and even though it becomes necessary to take out any one or more of the units entering into any one or more of the bracket supported courses, such repair work, also, may be done with economy of labor and time of shut-down; and these underlying purposes of the invention will be realized by instrumentalities which are exceedingly economical in first cost as compared with lining supports built upon the principle of a trussed steel framing; and such economy will extend as well to considerations of replacement of supporting units, in cases where they may become impaired through neglect of the lining.

In the accompanying drawings, which show the preferred embodiment of the several parts of the invention Figure 1 is a perspective view of a portion of a furnace wall. and its lining constructed of brick-like building units arranged with an air space between the lining and the wall, and having the supporting units incorporated in the wall structure and in spacing relation to key units of the lining structure.

Figure 2 is a horizontal section of a portion of Figure l in a plane immediately above two adjacent supporting units, the plane of section being suggestedby the line 2--2 in Figure 4.

Figure 3 is an inside face view of a typical portion of lining wall, with the relation of the supporting unit to a key unit indicated in dotted lines.

Figure 4 is a vertical section on the line 44 of Figure 3.

Figure 5 is a perspective View of one supporting units.

Figure 6 is a perspective view of the tie clip which drops into engagement with asupporting unit, and the key unit mounted thereon in order to interlock said units against horizontal displacement or tipping under loads inherent in the of the lining.

by present experience in the art of furnace walls.

B represents a furnace lining constructed of building blocks 2, 3, 4, of a constituency approe priate for high temperature uses but which pref:- erably differ in dimensions and-design; blocks 3 being what are herein termed key units in that they are mounted upon the supports C and afford sustention to the building course in which they are incorporated; blocks 4 being wedge units intermediate of and cooperating with the blocks 3 to complete an arched course (flat, in the illustrative instance) and blocks 2- constituting filler units located between vertically Spaced, bracket 105 supported arch courses to complete the wall under conditions which make these filler units readily removable and replaceable without disturbing the arch courses, or with disturbance of only immediately concerned units of the arch n course in case of impairment of the latter. In the illustrative embodiment, single arch units 4 are shown between each two key units 3. These two types of units meet through wedge faces which adapts each wedge unit to be sustained by two key units, the resultant arched course being, of course, suitably sustained at its respective ends in accordance with the principles of masonry. But no limitation is to be imputed from the disclosure of a single wedge unit rather than a plurality thereof, it being equally well known in wall masonry that by .proper selection of impinging faces more than one intermediate supporting unit could be employed.

C represents supporting .units which, by reason of their block or brick-like body portions 5, are readily incorporated into "the structure of the Wall 1 in positions to extend transversely therethrough and present their inner ends into supporting and interlocking relation to certain of the units of the lining B. The body portion 5 preferably is flanged, as suggested .at 5a, to more firmly anchor it in the structure of wall .A, and it carries upon its inner end a depending .on'the clip 8 and thusbecomes horizontally inter-- locked with or yoked to the flange 7 of the support C and 'held against tipping under its own weight or loads imposed upon it in the lining. Key unit 3 is preferably formed with a lug 3a beyond its groove 3b .as the portion through which it is received by the ledge 6a, and this lug also serves as a spacing element which defines the air space D with which the furnace is preferably constructed.

Some of the important advantages arising from a plurality of segregated individual unit supports andtheir independent supporting and interlocking relation to individual key'units-of the lining are the low initial cost of the supportawhieh may :be simple box-like castings; the ease with which they can be incorporated with and replaced in "the body of the wall; the wide latitude of election in the positioning of these supports conformative with desired location .of key'members with which they are to cooperate; the maintenance of freer circulatory 'air space between the lining and the wall, as compared with elaborate trussedsteel "framing upon which the lining units are usually mounted; the opportunity to design .the key unit in' a manner to adapt it to define the spacing of the lining from the wall; and the facility with which the key unit and support can be brought into interlock with a minimum displacement of surrounding liner units.

"What is'claimed is:

1. In a furnace or the'like, a masonry confine of'the type comprising an outer wall and a rene'wable lining wall vertically supported largely from the outer wall, a key unit incorporated in the structure of the lining wall and having a portion, through which'it is supported, presented toward the outer wall, a supporting unit for said key unit and having a body portion incorporated into the structure of the outer wall and carrying at its inner end a bracket portion presented in position to engage beneath and vertically sus-' inwhich the body portion is of brick or block-like form and is adapted to take the place of a building unit in the outer wall.

l. A supporting unit as described in claim 1, in which the body portion is of hollow box construction, the bracket portion depends from the inner end of the lower wall of said box construction and (carries an inwardly presented supporting ledge, and the tie member includes a yoking flange forming a continuation of the upper wall of the body construction.

5. A supporting unit as described in claim l, in which the tie member comprises a yoking flange forming a continuation of the body portion and having aneye, and the clip having a portion adapted to engage in said eye and a portion adapted to interengage with the key unit of the'lining.

6. In a furnace 'or the like, a masonry confine of the .typecomprising an outer wall and a renewable lining wall vertically supported largely from the outer wall, and in which the lining is spaced from the outer wall, key units incorporated in the structure of the lining wall and each having a projection presented into the space between the walls, supporting units for the respective key units, each having a body portion incorporated into thestructure of the outer wall and carrying upon its inner end a bracket portion presented I 1' in the space between the walls and in position to engage beneath a projection of the respective key units and thereby a'fiord vertical support to said key-unita'andtie members also in the interwal'l space,'anc'hored to the respective supporting 'units in planes materially above the bracket portions thereof and 'interengaging with the supporting projections of the respective key units in a-direction which is horizontally outward and thereby preventing inward tipping of the key .units .on'the'bra'ckets.

7. A furnace wall structure as described in claim 6, in'which the projection on the key units constitute spacing lugs which determine the relation of said units tothe wall.

8. A furnace "wall structure as described in claim'fi, in which the projection on the key units constitute lugs which determine the positions of the key units relatively to 'the outer wall, said lugs provide interlockinggrooves, and the the members of the supporting units include clips
